Abstract : We present a search for new physics in events with two high pT leptons of the same electric charge, using data with an integrated luminosity of 6.1fb-1. The observed data are consistent with standard model predictions. We set 95% C.L. lower limits on the mass of doubly charged scalars decaying to like-sign dileptons, mH±±>190-245GeV/c2, assuming 100% BR to ee, μμ or eμ.
